SPECIFICATION forming part of Letters Patent No. 460,152, dated September 29, 1891.

Application filed December 13, 1888- Serial No. 293,495. (No model.)

To all whom it may concern.-

Be it known that I, ORVILLE M. MORSE, a citizen of the United States, residing at Jackson, in the county of Jackson and State of Michigan, have invented new and useful Improvements in Dust-Collectors, of which the following is a specification.

This invention relates to a dust-collector having a separating-chamber provided with an imperforate peripheral wall and a rotating fan arranged within the separating-chamber, whereby the dust-laden air is caused to whirl in the separating-chamber and the dust is massed by centrifugal force against the imperforate peripheral wall, along which it passes to the dust-outlet, while the purified air passes toward the axis of the separating-chamber, where it escapes.

The object of the present invention is to simplify the construction of the machine.

Theinvention consists of the improvements which will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, consisting 2 5 of two sheets,Figure 1 is a sectional elevation of a dust-collector provided with my improvements. Fig. 2 is a horizontal section in line 00 as, Fig. 1. Fig. 3 is a sectional elevation showing a modified construction of the dust-collector. Fig. 4 is a horizontal section in line 3 3. Fig. 3.

Like letters of reference refer to like parts in the several figures.

A represents the peripheral wall or case of the separating-chamber of the dust-collector, composed of a tapering lower or main portion a and an upper cylindrical portion a.

Bis the head which closes the upper end of the separating-chamber and is provided with a central opening Z2.

C is the air-outlet tube arranged in the opening I) and made smaller in diameter than said opening, so as to leave an annular passage between the tube and the edge of the 4 5 opening for the ingress of the dust-laden air.

D is an air-trunk which is arranged on the top of the dust-collector and which communicates with the opening I) and supplies the dust-laden air to the machine. The air-outlet 5o tube C extends through the top of the airtrunk D.

E represents an internal head arranged within the separating-chamber opposite the junction of the cylindrical and tapering portions a a of the peripheral wall and having its edge separated from the peripheral wall by an annular opening e. e

F represents fan-blades arranged to rotate in the chamber G between the heads B and E, so as to draw the dust-laden air into this chamber through the opening I) and drive it with a whirling motion through the annular opening 6 into the separating-chamber below the head E. The fan-blades F are attached by arms h to a shaft H, which is arranged axially in the dust-collector and journaled in bridge-trees 2' and j, secured to opposite ends of the dust-collector. The arms 7L extend from the fanblades outwardly and downwardly through the annular opening a and below the internal head E to the shaft H.

K represents a brush or wiper secured to the shaft H within the air-outlet tube 0 and sweeping the inner surface thereof, so as to prevent the accumulation of dust on the same.

Z represents a pulley secured to the upper end of the shaft H for rotating the same.

at represents the dust-discharge aperture at the small end of the tapering separatingchamber.

M represents an inverted-cupshaped valve or trap secured to the shaft H above the dust discharge opening for checking the ingress of air, while permitting the escape of the dust.

The dust-laden air is, by the action of the fan-blades, drawn through the air-trunk D and opening 19 into the chamber G, whence it is expelled with a whirling motion through the opening (2 into the tapering portion of the separatingchamber. The air continues to whirl in the latter, whereby the dust particles are driven against the peripheral wall and discharged through the aperture m, while the air, freed from dust, moves toward the axis of the machine and escapes through the outlettube 0.

In the modified construction represented in Figs. 3 and at the arms N, to which the fanblades are attached, extend inwardly to the shaft H, and the outlet-tube is composed of Ion two sections 0 and 0, arranged, respectively, above and below the arms, the upper section 0 being secured to the air-trunk D and the lower section 0 to the internal head E. The fan-arms N are provided with an annular shield p,whieh covers the annular opening between the tube-sections O O.

I claim as my invention 1. The combination, with the separatingchamber having an imperforate peripheral Wall and a dust-outlet, of a central air-outlet tube, an inlet for the dust-laden air arranged outside of the air-outlet tube, and a fan arranged in the separating-chamber between its peripheral Wall and the inlet for the dustladen air, substantially as set forth.

2. The combination, with the separatingehamber having an imperforate peripheral Wall, a central outlet-tube for the'purified air, and an inlet for the dust-1aden air, of an internal head separated from the peripheral Wall by an annular opening, fan-blades ar- 20 ranged between the internal head and the end of the separating-chamber, an axial shaft, and arms extending from the fan-blades through said annular opening to the shaft, substantially as set forth.

WVitness my hand this 1st day of December, 1888.

ORVILLE M. MORSE.
